Besides being a lifelong friend, Dennis has been an invaluable aid in helping me with my nutritional
problems. Although a Chef, I at times eat the wrong foods. He is very experienced and well-versed in diagnosing your needs & recommending proper supplements. His advice changed the status of my overall health & fitness; he also updates my supplements when necessary. Chef Mike Borassi in LA

As a health practitioner for the past 35 years I've had many conversations with Dennis (over the years) & have been impressed with his knowledge of nutritional concepts & detailed biochemical
interactions. Also I'm pleased with his ability to tailor a plan which meets the awareness & possibility
of his clients' success in relation to their belief system. Dr. Dennis Casad, D.C.

recommend his services. Nancy Long, MSW
As part of Sonoma Valley Hospital's Integrative Network, Dennis has presented his insights at various
events on topics such as diabetes, stress & inflammation, thyroid health, dietary "resolutions," and
supplements. He is a great speaker with a wealth of knowledge & a living testimonial of his teachings. His background as a herbalist working in a pharmacy gives him a unique understanding of the balance between natural & pharmaceutical medicine. Steven Lewis, Wellness Coordinator, SVH
I would highly recommend Dennis for nutritional counseling & guidance through the confusing array of "advice" out there. He brings a grounded foundation of validated science-based nutrition with a practical understanding of how to apply it to your specific needs.

He also is a skilled public speaker and non-judgmental in his approach. Paul Clark, Clinical Herbalist

impressive catalog of education & practical experience; his breadth of knowledge is remarkable, and he's approachable, warm, and without pretense. Celina Briggs, MBA, (Integrative Pharma Manager)
I've known Dennis for 6 years, and we've had many discussions concerning the role Nutrition plays in a person's health & vitality - a subject I'm interested in as a Registered Nurse & advocate for my own health. Apparent to me during this time is the wide range of knowledge that he has & how committed he's been to his interest in "functional healthcare." Vaughn Adkisson, RN
I've known Dennis for well over 20 years, and I'm constantly impressed by his depth of knowledge &
his remarkable ability to share this with people in an effective & straightforward way. He takes
complex information & makes it accessible & understandable. I'd highly recommend him to anyone.
